(Thailand sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

sanitation truck hydraulic cylinder are widely used in Thailand，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed sanitation truck hydraulic cylinder for customers from Thailand.

Introduction to sanitation truck hydraulic cylinder:

sanitation truck hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards sanitation truck hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the sanitation truck hydraulic cylinder guide is determined by the length of the stroke. Check the strength of sanitation truck hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

If the sanitation truck hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the sanitation truck hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow sanitation truck hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the sanitation truck hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the sanitation truck hydraulic cylinder includes the leakage caused by excessive wear of the sanitation truck hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and sanitation truck hydraulic cylinder, and the phenomenon of "pulling the sanitation truck hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

sanitation truck hydraulic cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

Under normal circumstances, the sanitation truck hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the sanitation truck hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the sanitation truck hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the sanitation truck hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the sanitation truck hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about sanitation truck hydraulic cylinder:

How to change the seal ring of lift oil cylinder of forklift truck?
Remove the cylinder, put it on the vise, first screw off the big nut plug on the head, and then pull out the guide sleeve, you can directly pull out the core of the cylinder, if it is to change the seal of the cylinder head, the core does not need to be pulled out, if it is to change the seal inside, pull it out and see the oil seal, remove it and replace it, there are three seals of the cylinder head, the inner seal, The outer seal, dustproof, it is best to replace them all together, and be sure to keep them clean when changing, and you can lubricate them with clean hydraulic oil.

What is the rated pressure of the general cylinder?
This depends on the model of the cylinder, 1. The rated pressure of the light tie rod cylinder is 7 series 7MPa and 14 series 14MPa. 2. Rated pressure of engineering cylinder 16MPa. 3. Rexroth type metallurgical cylinder rated pressure 250MPa.
